For very advanced beginners or intermediate level knitters. This unisex, scarf is knit in the English Rib stitch (also called the "mistake rib") with a thick twisty cable straight down the middle. For a thick, cushiony, chunky scarf you would use size 4 yarn and slightly too thin knitting needle size (for ex. 10mm diameter needles). For a wider, looser, flowier scarf use fatter needles.
